Remove directory from address in Joomla

So you want to run your site from a sub-directory on your FTP, but you do not want to have that directory display as part of your web address? Well, the solution is very simple (and does not even need a manual .htaccess change) and I am surprised I did not discover this sooner.

Solution

In your configuration.php of your Joomla! site, edit the $livesite parameter value, and do not leave it empty. You will then add your address without the sub-directory in the address, eg. if you website sits in domain.com/joomla/ and you want to display only domain.com/:

$livesite='http://domain.com';

This will display all URL's on the site without the sub-directory. Simple.
